Abstract: A process for graphic display of network performance information includes querying a number of platforms serving communication network functions for performance data, scaling such data to a scale of colors, displaying hierarchically linked sets of graphic objects which are color coded to represent the performance of network functions with which they are associated. Graphic selection of an object can either cause immediate display of related numeric information or can cause the display of a lower level set of objects which may be color coded to performance indexes, conventional graphic renderings of data, or alphanumeric expressions of data. The process enables effective monitoring of a complex operation and expedites isolation of network problems.
